Error:Attribute "orientation" has already been defined about android-flowlayout

[ApmeM]

I do not understand the problem.
Where is it defined?
Where this error appears?
How should I create prefixes? In xml prefixes created like namespace with xmlns.
The title says nothing....

You defined an "orientation" attribute in attrs.xml for your FlowLayout, BUT since custom attributes must be unique, if I include the gridlayout v7 support library for example (com.android.support:gridlayout-v7), the compilation will simply fails because that custom attributes already exists in that library.

You should prefix your custom attributes to avoid collisions, or use those already defined by the system (like "android:orientation"):

<declare-styleable name="FlowLayout">
    (...) 
    <attr name="android:orientation"/>
</declare-styleable>

Hi,

aha, thank you. I think I'll use android:orientation then.

I did not know about it.

Thanks.

Hi,

I have updated code to use android:orientation
Can you check now if it is ok.

Thanks.

Hi,
I have got a same error today: "Attribute "orientation" has already been defined" , use a com.android.support:gridlayout-v7 lib also. Looking for solving...
ps. I am new to Android, so I could be wrong.

Can you try latest commit from this repository?
It was fixed and moved to android:orientation, so I think this error cant appear any more.
What commit are you using?

I do't know, I was using Gradle in the way you have described. I will try it later. Thank you.

Just download the latest source to get the fix.
